Description

Technical Field

[0001] This invention belongs to the technical field of bulk material storage buildings, and relates to a C-type material yard retaining wall and its modification method. Background Technology

[0002] In the field of bulk material storage, Type C enclosed stockyards have become the preferred environmentally friendly stockyard type for industries such as steel, ports, and metallurgy due to their outstanding advantages such as large storage capacity, small footprint, and good environmental performance. Their typical characteristic is that a longitudinally continuous retaining wall is typically installed in the middle of the stockyard, dividing it into two or more storage sections. This allows for the separate storage of different types of materials, significantly improving the storage flexibility and material variety capacity of the stockyard.

[0003] However, some enterprises, during the initial construction phase, opted for column structures instead of complete reinforced concrete retaining walls for their central support structures, either because the planned storage materials were relatively simple or to control initial investment costs. While this column structure reduced initial civil engineering investment and concrete work, its inherent limitations restricted the full utilization of the material yard's functions: firstly, the storage compartments on both sides of the columns could not be effectively separated, requiring the storage of the same type of materials, thus limiting the number of material types that could be stored; secondly, during stacking and reclaiming operations, the height difference between the material piles on both sides of the columns needed to be strictly controlled to prevent one side from collapsing and causing a safety accident, and "dead material zones" that were difficult for equipment to access could easily form between the material piles, increasing the difficulty and workload of cleaning operations.

[0004] As enterprises develop their production, the variety of materials tends to increase. The traditional C-type material yard with its central pillars, due to its structural limitations, struggles to meet the growing demand for storing a wider variety of materials, and its significant storage space advantage cannot be fully realized. Therefore, there is an urgent need for a new type of retaining wall structure and corresponding renovation construction methods. This would allow for the safe, economical, and efficient upgrading of existing C-type material yards into standard C-type material yards with multi-variety storage capabilities, without affecting the original main structure and normal production. This would fully unlock the design potential and improve the operational efficiency and flexibility of the material yard. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a C-type material yard retaining wall and its modification method, thereby transforming the existing intermediate column C-type material yard into a material yard capable of storing more material varieties, so as to give full play to the advantages of C-type material yards in terms of large storage capacity and large number of stored varieties.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A method for modifying a C-type material yard retaining wall includes the following steps: Between the existing longitudinal columns in the existing material storage area, several additional longitudinal beams with a certain distance between them are added so that the materials cannot completely cross the longitudinal beams when naturally stacked, thus achieving a natural separation effect. This transforms the existing column-type C-shaped material yard into a material yard capable of storing more types of materials.

[0008] Furthermore, the spacing h between adjacent longitudinal beams is less than or equal to b / 2*tanα, where b is the width of the longitudinal beam and α is the maximum natural angle of repose of the material, so that the material cannot exceed half the width of the longitudinal beam in its natural stacking state, thus achieving the function of natural separation.

[0009] Furthermore, the spacing h between adjacent longitudinal beams is less than or equal to b*tanα, where b is the width of the longitudinal beam and α is the maximum natural angle of repose of the material, so that the material cannot completely cross the width of the longitudinal beam in its natural stacking state, thus achieving the function of natural separation.

[0010] Furthermore, the newly added longitudinal beams are parallel to each other.

[0011] Furthermore, the newly added longitudinal beams and the existing longitudinal columns form a grid structure that interweaves horizontal and vertical elements.

[0012] Furthermore, the upper half of the cross-sectional structure of the longitudinal beam is a triangular structure to reduce the formation of dead material.

[0013] Furthermore, the triangular structure of the upper half of the longitudinal beam is a filler material, which is one or more of foamed concrete, concrete bricks, clay bricks, sand-lime bricks, and stones.

[0014] Furthermore, the longitudinal beam is connected to the existing longitudinal column by inserting reinforcing bars into the existing longitudinal column.

[0015] Furthermore, the longitudinal beam is connected to the existing longitudinal column by assembly bolts, and the longitudinal beam is a steel structure beam.

[0016] On the other hand, the present invention also includes a C-shaped material yard retaining wall, which is modified according to the above-described modification method.

[0017] The beneficial effects of this invention are as follows: This invention provides a C-type material yard retaining wall and its modification method. By adding longitudinal beams spaced at certain intervals between existing longitudinal columns, a crisscrossing mesh structure is formed. The maximum natural angle of repose (α) of the material limits the spacing between adjacent longitudinal beams (h≤b / 2*tanα) or h≤b*tanα, preventing material from crossing the beams during natural stacking, thus achieving natural separation. This design fully utilizes the physical characteristics of bulk materials, preventing material flow and upgrading the original column-type C-type material yard into a multi-variety storage system. It fully leverages the advantages of large capacity and flexibility, effectively improving the operational efficiency of the material yard.

[0018] Compared to the traditional method of directly adding new concrete partition walls, this invention adopts an online modification approach, requiring only the addition of longitudinal beams (such as steel structural beams connected by bolts or fixed with rebar) between the columns, significantly reducing investment costs and the amount of concrete work. Furthermore, this method is highly adaptable, can be implemented without interrupting normal production, has a short modification cycle, minimizes interference with the main structure of the material yard, and ensures safety and efficiency.

[0019] Furthermore, the upper part of the longitudinal beams can be optionally structured into a triangular shape (filled with materials such as foamed concrete), which can reduce the formation of "dead material zones" and improve material clearing efficiency. Other advantages of this scheme include easy adjustment of the spacing to accommodate different material repose angles, as well as the stability of the mesh structure, further tapping the potential of C-type stockyards and providing an economical and practical upgrade path for industries such as steel and ports.

[0023] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0024] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual pictures. They should not be construed as limiting the invention. To better illustrate the embodiments of the invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting the present invention. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0026] like Figures 1-2The diagram shows a storage area 2 of an existing C-type material yard 1 when no materials are stored. As can be seen from the diagram, the storage area mainly includes a storage base plate 3, several longitudinal columns 4 arranged side by side, a T-shaped platform 5 set on top of the longitudinal columns 4, and several short columns 6 set on the T-shaped platform 5.

[0027] like Figures 3-4 The diagram shows a schematic of the storage area 2 of the existing C-type material yard after storing material A 7. As can be seen from the diagram, since the middle structure of the storage area is a longitudinal column 4, and the longitudinal column 4 has basically no material blocking effect, the material A 7 located on both sides of the longitudinal column 4 is interconnected and must be of the same type.

[0028] Example 1 like Figures 5-6 The image shows the state of the C-type material yard in this embodiment when no materials are stored. Specifically, the C-shaped material yard includes an existing C-shaped material yard 1 and longitudinal columns 4 set in the storage area 2 of the C-shaped material yard 1. The longitudinal columns 4 are the existing longitudinal columns in the existing C-shaped material yard 1. Several longitudinal beams 9 with a certain distance between them are added through structural modification. Because the spacing between adjacent longitudinal beams 9 is limited, the material cannot completely cross the longitudinal beams in a natural stacking state, thus achieving the function of natural separation.

[0029] Preferably, in this embodiment, the spacing h between adjacent longitudinal beams 9 is less than or equal to b / 2*tanα so that the material cannot cross half the width of the longitudinal beam in a natural stacking state, thus achieving the function of natural separation, where b is the width of the longitudinal beam and α is the maximum natural stacking angle of the material.

[0030] Preferably, in this embodiment, the longitudinal beams 9 between the longitudinal columns 4 are parallel to each other.

[0031] Preferably, in this embodiment, the newly added longitudinal beams 9 and the existing longitudinal columns 4 form a grid structure with intersecting horizontal and vertical lines.

[0032] Preferably, in this embodiment, the longitudinal beam 9 is connected to the existing longitudinal column 4 by assembly bolts, and the longitudinal beam 9 is a steel structure beam. This connection structure is existing technology and will not be described in detail.

[0033] like Figures 7-8 The figure shows the state of the C-type material yard after storing materials in this embodiment. As can be seen from the figure, this embodiment makes full use of the physical properties of the bulk materials themselves, namely the natural angle of repose. The longitudinal beams 9 set at intervals prevent the materials on both sides from communicating with each other. Corresponding to the longitudinal column 4 on the left is material A 7 and the longitudinal column 4 on the right is material B 8, thereby realizing the storage of more material varieties and meeting the functional requirements of storing multiple types of materials.

[0034] Example 2 The difference between this embodiment and embodiment 1 is that, in this embodiment, the upper half of the cross-sectional structure of the longitudinal beam 9 is a triangular structure to reduce the formation of dead material.

[0035] In addition, in this embodiment, the triangular structure of the upper half of the longitudinal beam 7 is filled with foamed concrete. Furthermore, in this embodiment, the longitudinal beam 7 is connected to the existing longitudinal column 4 by anchoring reinforcing bars to the existing longitudinal column 4.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
